Account Help

So this is going to be a strange question but years ago I used to play on this server a lot. My username was sam6882 and I was a high level warrior (98-100, cant remember exactly). However, I have lost access to this minecraft account and Mojang has not been all too helpful in recovering it. I have receipts from many purchaes I have made on the server and was hoping they could be used as some form of proof. My main question is, and I understand if its impossible, but if it would be possible to transfer the data for my old account sam6882 to a new minecraft account I have made? I would be unbelievably appreciative if you could help but I understand if not.

Thank you for your time, Sam Preston

 

Your class? maybe. Your items? No.
